WOOD-TURNING MACHINE.

SPECIFICATION forming pact of Letters Patent No. 365,277, dated June 21, 1887.

Application filed August 30, ISM). Serial No. 212,210. (No model.)

To all whmn it 72mg concern.-

Be it known that I, ADOLPH SOHUCH, acitizen of the United States, residing at Sacramento, in the county of Sacramento and State of California, have invented a certain new and useful \Vood-Turning Machine, of which the following is a specification.

My invention relates to carving or turning parts of furniture and decorative wood-work, such as table and chair legs, &c.; and the object of my invention is to facilitate the duplication of such parts as occur in sets of furniture and balustrades.

The improvements which I have made will be fully understood from the following description, when taken in connection with the annexed drawings, in which- Figure 1 is a top view of my improved machine. Fig. 2 is an elevation of the right-hand side ofthe machine when thepattern or copying cylinder is at its highest point, indicating by dotted lines the work in position. Fig. 3 is a front elevation of the machine. Fig. 4 is an enlarged diametrieal section through the copying-cylinder and its immediate attachments, the section being taken in a plane from front to rear. Fig. 5 is an enlarged front view of the vertically-movable carrier or sash. Fig. 6 is an edge view, having the adjustable pattern applied to it, and showing part of the rod which connects the tool-rest to it. Fig. 7 is a top view of the perforated chuck or bolt-holder shown in Fig. 4.

Referring to the annexed drawings by letters, A designates the bed or main frame, which is mounted on legs B and preferably made of cast-iron, so as to afford solidity.

A A are horizontal parallel guides for aforward and backward reciprocating carriage, b, on which is applied a laterally-adjustable slide, 1), bearing a toolrest, Zr, to which is suitably secured a turning or carving tool, If. The slide 1) is adjustable by means (indicated in dotted lines, Fig. 3) of a screw bearing on one end a hand-crank, b, in a manner common to turning-lathes. This screw is tapped through a boss depending from the lateral slide Z).

O O designate standards rigidly secured to the sides of the frame Aand bearing V-grooved guides O O at their upper ends, which constitute guide bearings for the vertically arranged tongues or portions tof a vertically reciprocating carrier or sash, D. The lower horizontal portion, '6, of this carrier D moves in vertical guides D D, shown in Fig. 8.

E designates a horizontal shaft bearing fast and loose belt-wheels and having a slotted crank, G, keyed on one end, the wrist-pin of which is pivoted to a block. H, that plays in a slot, 1?, in the cross-head L of the sash or carrier D. By these means when rotation is transmitted to the shaft E a vertical reciprocating motion is transmitted to the said carrier. This carrier has rigidly secured two brackets, fand g, for holding in a vertical position the cylindrical pattern or copying cylinder 0. This cylinder is allowed to rotate horizontally, and it is centered at its upper end by means of a pointed screw, f, in braeketf, and its lower end is centered by aeollared journal, ffiwhieh is screwed on a contractiomf, of the cylinder 6, and is received in an aperture through the lower bracket, 9, as shown in Fig. 4. To this collared journal f perforated for the pin f, is secured by means of a tenon,f", a bolt-chuck,

f", which has a number of perforations, f,

through its flange, adapted to receive a removable pin, f, for the purpose of uniting the chuck to the part f 2 in an adjustable manner, so that by removing said pin the chuck proper can be adjusted and set at pleasure according to the distance apart of the perforationsiu the said chuck.

To the upper end of standard 0, that is on the left-hand side of the frame, is rigidly secured an arm,j, to the inner end of which is pivoted a follower, t, which is free to move in a spiral groove, 1', in the periphery of the cylinder 6. By these means the cylinder 6 is rotated in one direction during the ascending strokes of the sash or carrier D, and it is rotated in an opposite direction during the descending strokes of said sash or carrier.

It designates a bracket or foot, which is vertically-adjustably secured to the upright portion of the carrier D by a bolt, 8 and nut s, the bolt passing through the vertical slot 8 in the upright part of the carrier D and recciving the said nut on it, and provided with an adjustable center bearing, 9", for the lower end IOC 20 f and upon the center pin, 1'.

of a bolt or stick when in position to be acted iii n by the tool b, as indicated in dotted lines, .ig. 2. L designates the pattern for giving the desired taper to the stick, chair-leg, or other article. This pattern is pivoted at a to the right-hand edge ofthe vertically-reciprocating carrier D, and its lower arc slotted end, s is adj ustably secured to said edge of the carrier by means of aset-screw, The edges of this pattern are exactly parallel to each other and are embraced bythe bifurcated end a of a connectingrod, a, which is endwise adjustably secured to the carriageb, which bears the toolslide and its tool Z).

The operation of the machine is briefly as follows: A pattern-cylinder, e, of the required kind, is adjusted to the bracketsf g, and the bolt or stick to be cut is adjusted in the chuck The required taper to be given to the stick being determined, the pattern L is adjusted for such taper. Mo-

tion is then imparted to the shaft 1*] and the stick properly turned. After once adjusting the machine the articles turned will be exact duplicates of each other in size and shape.

During the operation of finishing a stick, if it is desired to adjust the article about its axis for any purpose without rotating the patterneylinder e, the motion of the machine is stopped and the pin f removed.- The stick and its flanged chuck are then adjusted about their vertical axis as required and the pin f again inserted.

Having described my invention, I claim- 1. In a wood-turning machine, the combination, with a suitable frame, of a verticallyreciprocating carrier, a spirally-grooved patand the laterally-adj ustable tool-bearing slide,

substantially as described.
